A: Butt cheek sex, aka gluteal sex, is when a man stimulates his penis by inserting it in between the butt cheeks in the intergluteal cleft (aka butt crack) without actually penetrating the anus.

Pygophilia is the psychological term for sexual arousal focused on the buttocks, or a butt fetish.

For almost 20 years, the gluteus maximus has become a cultural phenomenon, with some people’s gluteus more maximus than others.

Big booty, bubble butts, and twerking were all brought in vogue due to the shapely derrieres of celebs including J-Lo, Beyoncé and Kim Kardashian.

This obsession with large tushies has led to an increase in butt augmentation including butt implants and a process known as the Brazilian Butt Lift that promises to increase your glutes 1 to 2 sizes larger with fat injections for a mere 10K.

Anal sex has also become more mainstream with more heterosexual couples trying out this once taboo sex act, while prostate play has increased in popularity among straight men.

But, for those of us who don’t want to experience anal sex, there are still ways to enjoy sensual butt play without actual penetration.

Enter intergluteal sex, also called gluteal sex, or referred to as an ass job, butt job, butt cheek sex and a hot dog.

Gluteal sex can be done in several ways. One is when the guy slides his penis between his partner’s butt cheeks, as stated above. The other way is when his partner sits on top of his lap and grinds their butt against his penis.

It is generally considered a form of safer sex, as penetration does not take place.

However, if both partners are naked, be careful, because if sperm happens to get in a woman’s vulva, she could actually get pregnant. And, you also have to consider the transmission of STIs as well including herpes, HPV and pubic lice.
